This research aims to determine student motivation towards the Relating, Experiencing, Applying, Cooperating, Transferring (REACT) learning strategy. The population in this study were all class VIII students at SMP Negeri 3 Subang for the 2023-2024 academic year. Sampling used a purposive sampling technique, samples taken from class VIII C were 34 students as an experiment. The experimental class was given learning using the Relating, Experiencing, Applying, Cooperating, Transferring (REACT) model to determine students' motivation for learning mathematics and mathematics questions. The instrument used in the research was a non-test in the form of a questionnaire. Questionnaires were distributed after the Relating, Experiencing, Applying, Cooperating, Transferring (REACT) model learning was carried out to find out whether students' motivation in learning mathematics and completing mathematics questions increased. The scale used in this research is the Likert scale. Based on the results of the data in this study, it shows that motivation for students who show interest in learning mathematics gives positive results with an average score of 4.0. Students' learning motivation towards the Relating, Experiencing, Applying, Cooperating, Transferring (REACT) model learning strategy gave positive results with an average score of 4.1. Students' learning motivation towards mathematical problem abilities gave positive results with an average value of 4.2. So it can be concluded that learning with the Relating, Experiencing, Applying, Cooperating, Transferring (REACT) model can be used as an alternative in mathematics learning that can raise students' enthusiasm and motivation.

PENGARUH MODEL PEMBELAJARAN CORE (CONNECTING, ORGANIZING, REFLECTING, EXTENDING) TERHADAP KEMAMPUAN BERPIKIR KRITIS MATEMATIS

2024-06-29T05:59:09+07:00

The ability to think mathematically critically in learning mathematics is essential for students to understand and help solve a problem in math. The ability to think critically mathematically is very low. One of the learning alternatives that can be used in training mathematical critical thinking skills is through the CORE learning model. (Connecting, Organizing, Reflecting, Extending). The study aims to find out whether the influence of students' ability to think mathematically critically has been achieved on the higher CORE learning model among students who obtained expository learning. The method used in this research is semu experiment (quasi experiment) with non-equivalent control group design, the subject of this study is a student of class XI High School Pasundan 3 Bandung. Sampling techniques use purposive sampling, using two classes: experimental class and control class.
